Cobalt Blue Dwarf Gourami require a tank that is 40Litres or larger. The aquarium should be heavily planted and have at least part of the surface covered with floating plants. A darker substrate will help show-off the gourami’s colors, and peat filtration is recommended. Regular water changes are a must, as this gourami can be susceptible to disease. They should not be kept with large, aggressive fish, but are compatible with other small, peaceful fish as well as fellow gouramis. Loud noises often scare them, so the tank should be in a quiet area.
Cobalt Blue Dwarf Gourami is an omnivore and prefers both algae-based foods as well as meaty foods. An algae-based flake food, along with freeze-dried bloodworms, tubifex, and brine shrimp will provide these fish with the proper nutrition.
